Hello

I have been driving my g/f's Fiesta

It is a 54 plate Fiesta Finesse with the 1.25 engine.

Basicly the revs drop at junctions and the car nearly always stalls its as if it idles too low.

What sensors can cause this problem.

My brother had something like this on his ST, think it was the airflow mass meter plug had fell out and wasnt getting the right reading so eventually cut out!

Check all around your manifold etc for good connections i guess?

Hi Jack

Everything checked and connected.

Anyone else have any ideas surely there is someone who has the answer.

Hmmmmm im only an amatuer so i dont want to give you advice thats wasting your time. Id say get a diagnostic check if all else fails but they are pretty pricey!

Idle speed control valve, controls the revs at idle and stops the car from stalling when the revs drop on deacceletion.

or throttle position sensor which senses the amount your pressing the pedal and sends a signal back to the PCM, that comes part of the ETB (electronic throttle body) ford have a recall for this which envolves replacing the wiring loom, ETB and PCM (Powertain control module) later calibration.

hope that helps
